Intel386 DX

The Intel386 DX has the following features including Object Code Compatible with All 8086 Family Microprocessors;Virtual 8086 Mode Allows Running of 8086 Software in a Protected and Paged System;Hardware Debugging Support;Numerics Support via Intel387TM DX Math Coprocessor;High Speed CHMOS IV Technology;132 Pin Grid Array Package;132 Pin Plastic Quad Flat Package.

The Intel386 DX Microprocessor is an entry-level 32-bit microprocessor designed for single-user applications and operating systems such as MS-DOS and Windows. The 32-bit registers and data paths support 32-bit addresses and data types. The processor addresses up to four gigabytes of physical memory and 64 terabytes (2**46) of virtual memory. The integrated memory management and protection architecture includes address translation registers, multitasking hardware and a protection mechanism to support operating systems. Instruction pipelining, on-chip address translation, ensure short average instruction execution times and maximum system throughput.The Intel386 DX CPU offers new testability and debugging features. Testability features include a self-test and direct access to the page translation cache. Four new breakpoint registers provide breakpoint traps on code execution or data accesses, for powerful debugging of even ROM-based systems.Object-code compatibility with all 8086 family members (8086, 8088, 80186, 80188, 80286) means the Intel386 DX offers immediate access to the world's largest microprocessor software base.

VCC and GND connections of the Intel386 DX must be made to multiple VCC and VSS (GND) pins. Each VCC and VSS must be connected to the appropriate voltage level.The circuit board should include VCC and GND planes for power distribution and all VCC and VSS pins must be connected to the appropriate plane.Information in this document is provided in connection with Intel products.
